I think you'd agree Jeff, that life is about balance. Could it be that by cutting out so many "bad things", you've actually just deprived yourself and your overall happiness is suffering?
Smoking is bad for your health, that's obvious, but a cigarette here and there isn't gonna poison or kill you. The same with alcohol, junk food, tv, gambling, etc.
I think it's actually silly to claim anything is inherently bad. They can all be used to your benefit or detriment. Lot's of people claim that money is evil, yet you don't believe that because you understand it's a tool.
